Can't find object in space

Hi SU community! Please help! I went to so a section cut of the ceiling and it is WAY bigger than the model. I think there is a hidden object somewhere in space, but I can’t find it, and there is nothing visible.

Any ideas of how to find where it is?

Thanks !

The section plane ought to give you some idea of where to look. Turn on Hidden Geometry and Hidden Objects, make sure all tags are visible. Then do right to left selection fences around the “empty” space and see what Entity Info shows. If it’s not something you need, hit Delete.
